2.15 Tractor Break-in
Before the tractor is put into service, it should run for a certain period under the specified conditions of
lubrication, rotational speed and load, and at the same time have any necessary inspection, adjustments and
maintenance, to normalize its technical state; a process called break-in.
If the break-in procedure is not followed
the warranty may be void.
2.15.1 Break-in Preparations
•
Perform per shift technical maintenance and 50 hour technical maintenance for the tractor during break-in.
(See “Maintenance Instructions”
in this Operation Manual).
•
Check and tighten the bolts, nuts and screws of the tractor.
•
Add grease to the grease cups of the front wheel hub, the kingpin of the front drive axle and the water pump
shaft. Check the oil level of the engine oil pan, the transmission mechanism and lifter, and the central drive
and final drive of the front drive axle. Add oil according to the specifications if necessary.
•
Fill the tractor with adequate fuel and coolant according to the specifications.
•
Check the tire pressure.
•
Check whether the electrical wiring is connected correctly and reliably.
•
Put all control handles in neutral.
2.15.2 Engine Idle Break-in
Implement a 15 minute idle break-in for the engine. After starting the engine in the sequence specified in the
Diesel Engine Use and Maintenance Manual
,
run the engine in three stages, i.e. low speed (the up position of the
accelerator), then medium speed (the medium position of the accelerator) and finally high speed (the down
position of the accelerator). Do each for 5 minutes. The throttle control handle can be used to set a constant engine
speed at all three stages.
During the engine idle break-in, check the state of the engine and the hydraulic oil pump carefully to determine
whether there are any abnormal sounds or any leakage of water, oil or air. Make sure that the instruments are
functioning normally. If any abnormalities are found, immediately stop the tractor to eliminate the faults, and then
continue the break-in process.
